Lens of Time: Velvet Worms—Secret of the Slime - bioGraphic
"With their chubby bodies, soft, padded feet, and slow-motion gait, South American velvet worms appear pretty harmless. Unless they’re hungry, and you’re an insect. Over millennia, these ancient creatures have evolved a pair of hunting weapons unlike any other in nature: dual high-speed canons capable of jetting viscous slime onto their prey from up to two feet away. Delivered with such power and speed, the velvet worm’s slime canon takes the element of surprise to new levels. And because the goo is delivered through narrow, flexible tubes and expelled with such tremendous force, it can cover a vast area in a matter of milliseconds.

Until recently, biologists still didn’t know exactly how these slime canons work. But then Andres Concha, a Chilean physicist who studies the physical mechanisms in biological systems, turned his attention to velvet worms. His goal: to better understand how fluids operate in the microscopic world. After collecting live specimens from southern Chile's remote temperate rainforest, Concha and his team used high-speed cameras to film slime canons in action. Their observations and measurements have provided new insights into the physics underlying this unique and deadly hunting tactic—and may one day lead to new biotechnology applications. Concha now applies his understanding of this mechanism—a unique adaptation that evolved some 500 million years ago—to construct working replicas of the slime canons in his lab."

Open-Assembly No:1. Loughborough. Insects, Worms, Mushrooms, Birds and Students | Dismal Garden
"An outdoor meeting and discussion place commissioned by Radar, Loughborough University that offers a situation where new associations between a variety of local actors can be explored. These actors include birds, insects, mushrooms, worms and students. The sculpture incorporates design elements from defensive street furniture, the ecology movement and the middle class British garden."

John Naughton: Of course worms can enter the net, that's the whole point | Media | The Observer
"So we're stuck with the trade-off between the creativity, innovation - and, yes, insecurity - that comes with openness; and the security - and stagnation - that comes with a tightly-controlled network. Which do we prefer? You only have to look at the data traffic for web pages and file sharing to know the answer."

isen.blog: Fixing the Internet might break it worse than it's broken now.
"So, we might ask, who wants the story of the dangerous Internet spread? Who wants the Internet to be seen as a dangerous place? Whose business models are becoming obsolete as the generic generative Internet grows and pervades? Who is threatened by the absence of gatekeepers? Then look who continues to pursue the story ..."
